(WBBM NEWSRADIO) -- A federal study shows measures to combat the spread of COVID-19 at Cook County Jail have been effective.
Cook County Sheriff Tom Dart says the study by the Centers for Disease Control and Prevention found that after expanded testing, mask-wearing, limiting detainee movement, and opening up previously unused parts of the complex, the spread of the virus within the jail slowed down significantly.
Dart on Wednesday said Cook County Jail is a model for other correctional institutions.
In March and April, Cook County Jail had more than 900 cases among detainees and staffers. Seven detainees died at hospitals after testing positive.
Dart says as of this week, only 11 detainees out of about 4,800 have tested positive for COVID-19.
He says eight of those detainees entered the jail with the virus.
